Visual Comparison
Comparison of 3D data from sensors in various conditions
3D sensors supply 3D data (depth image, distance measurements) and often 2D data (texture, standard colour images). Both 2D and 3D data is used to reconstruct view in VR.
Perspective from which VR user sees reconstructed view typically differs from that of the sensor.
In practice all 3D sensors provide 3D data with noise, artifacts and sensors are subject to limitations.
Aligned View
When looking at reconstructed 3D view from the same or similar perspective as 3D sensor, most 3D data imperfections are not visible (with exception for missing 3D data).

Side View
When looking at 3D reconstruction from the side compared to original sensor perspective we are able to see 3D data inaccuracy and noise.
